JP4848261B2 - Soundproof enclosure and construction method of soundproof enclosure - Google Patents

Description

  The present invention relates to a soundproof enclosure that covers the periphery of a power generator and a method for constructing the soundproof enclosure.

In recent years, large-scale hospitals, shopping centers, and the like have installed power generation devices as private power generation or emergency power supplies. Such a power generator is often installed outdoors, and therefore, it is necessary to take measures for waterproofing the power generator. Further, since noise from the engine or the like is generated when the power generator is driven, it is necessary to take a soundproof measure. Therefore, the power generation device is covered with a soundproof enclosure, and measures for waterproofing as well as soundproofing are taken (for example, see Patent Document 1).
Such a soundproof enclosure is not originally a building, but is a soundproof cover made of steel plate. Therefore, no building confirmation application is required. However, the structure has sufficient strength to allow the building confirmation to be approved. However, in the case of a large soundproof enclosure, there is room for being interpreted as a building rather than a soundproof cover. Therefore, it is assumed that a building confirmation application is made.

Thus, the soundproof enclosure 1 according to the present embodiment can be easily constructed on site.
Moreover, when the said construction method is used, although it is a panel construction method without a steel frame (column), it can be considered that the 1st connection member and the 2nd connection member correspond to the steel frame in a general steel structure. Therefore, it is possible to calculate the structure calculation based on the building structure calculation program, and to obtain a structure capable of responding to the building confirmation application.

(Other matters)
In the above embodiment, each of the first connecting member and the second connecting member also serves as a cover plate, but separately includes a cover plate and a first connection member that close the side opening of the wall panel, And you may comprise so that the cover plate and 2nd connection member which block | close the side part opening of a roof panel may be provided separately. If comprised in this way, it can be considered that the whole which added the cover plate to the 1st connection member and the 2nd connection member is equivalent to the steel frame in a general steel structure. Therefore, the strength of the entire panel assembly structure is increased.

  In the above embodiment, the front panel and the rear panel of the soundproof enclosure are not provided with a wall panel, and all of the soundproof galleries are mounted, but a part of the front panel and the rear panel is configured with a wall panel, The configuration may be such that soundproof louvers are attached to the remaining area.

  In the above embodiment, the soundproof enclosure is provided with the vertical soundproof gallery and the exhaust outlet is provided with the horizontal soundproof gallery. However, the present invention is not limited to this, and the soundproof enclosure is provided with both the soundproof enclosure and the vertical soundproof gallery. Alternatively, a horizontal soundproof gallery may be provided at both the intake and exhaust ports, or a horizontal soundproof gallery may be provided at the intake port and a vertical soundproof gallery may be provided at the exhaust port. However, since the vertical soundproof gallery is more expensive than the horizontal soundproof gallery, it is preferable that only one of the vertical soundproof gallery is a vertical gallery from the viewpoint of reducing the manufacturing cost. In such a case, it is preferable to provide a vertical soundproof gallery on the intake side from the viewpoint of preventing rainwater from entering. On the other hand, since the vertical soundproof gallery has a larger pressure loss than the horizontal soundproof gallery, it is preferable that only one of them is a horizontal louver from the viewpoint of the intake and exhaust efficiency of the outside air. In such a case, it is preferable to provide a horizontal soundproof gallery on the exhaust side from the viewpoint of preventing rainwater from entering. This is because the horizontal soundproof louver is inferior in waterproofness to the vertical soundproof louver, and it may be considered that rain enters the enclosure in the case of rain accompanied by strong winds such as typhoons. However, since the horizontal soundproof galleries are provided on the exhaust side, even if it is raining with strong winds such as typhoons, it is considered that rain will hardly enter the enclosure, so there will be no problem. is there.
